Application filed July 11, 1918. f Serial No. 244,408.

To all whom it may concern:

Be it known that I, JOHN Roox, Jr., a citizen of the 'United States, residing at Hamtramek, in the countyof Wayne, State of Michigan, have invented a new and use ful Shutter-Opener; and I do hereby de-- clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use 'the same.

The present invention relates to a shutter opening and closing device, and has for its object to provide a deviceof this character Which embodies novel features of construction whereby the shutters can be manipulated from the inside of a building with out the necessity of opening the-windows,

, thereby avoiding the necessity of letting a lot of cold-air and rain into a building and personally leaning out of awindow when it is'desired to close the shutters in bad weather.

., Further objects of the invention are to provide a shutter opening device which can e used in connection with the conventional shutters, which can be easily -manipulated from the inside of the building, which is adjustable to fit different window structures, and which canbe arranged to operate both blinds simultaneously.

Withthese and other objects in view, the invention consists in certain novel combina tions and arrangements of the parts as will more fully appear as the description proceeds, the ,novel features thereof being pointed out in theappended claims. a ,For a full understanding of the invention,

reference is tobehad to the following description and accompanying drawings, ,in

which:-

Fig. 5 is a front elevation of the lower corner of a window provided with shutters which are adapted to be opened and closed by a mechanism embodying the invention. vFig 6 is .a similar 'view of the inside of the window. 7

Fig. 7 is a top plan view sprocket wheel which engages the blind operating shaft. s

, Fig. 8 is a sectional view through the same. i s Y Corresponding and like parts are'referred to in the following description and .inditrate oneembodiment of the invention, the

reference character A designates a window casing which is of the' conventional construction, being provided with a sliding sash B and having a'sill 1v at the bottom thereof which overhangs. the outer face of thevwall C, a recess D being provided in the' wall under the/sill. A shutter E is hingedly connected to each side of the window casing A, *saidzshutters being adapted to be swung inwardly to close the window opening or swung outwardly away from the same in theusual and well-known man- The invention resides in the special means for mounting and operating the shutters, this mechanism enabling the shutterstosbe opened .and'closed from the interior ofthe building without the necessit of openingthe windows. 7 s

The lower shutter hinges each include a pair of complementalhinge leaves 2 and 3 which aresecured to the window casing A and shutter'E, respectively,-the leavesbeing formed at their meeting edges with knuckles 34: which receive a pintle 5, and the leaf 3 which is rigidly secured to the'edge of the shutter being constructed with a downwardly extending recessed arm 6 which is arranged in alinement with the axis of the hinge so that by applying the necessary turning force to this arm 6 the hinge, leaf 3 and shutter r ied ther y can be swung, back and of the small 'cated in all the views of the drawings by forth upon the axis of the hinge. Arranged under each of the shutter hinges is an upright shaft 7 which is shown as extending through the overhanging portion of the window sill 1, the lower end 7 of the shaft having a square or polygonal formation and being slidably received within a corresponding opening in the hub of a sprocket wheel 8. These sprocket wheels 8 have the hubs thereof journaled in bearings 9 which project outwardly from the wall C under the sill 1, the sprocket wheels and bearings being housed within substantially semispherical flanged casings 10 which are secured to the wall and which are provided with upper and lower openings to receive the upright shafts 7. The upper ends of the shafts 7 are connected by a series of links 11 to the blind hinges, the upper links being fitted; within. the recessed arms 6 of the respective hinges and held rigidly in position therein by suitable means such'as the set screws 12,, and the joints 11 between the members having arms at substantially right angles to each other so that a universal joint is provided between each of the upright shafts 7 and the upper link member which is connected to the corresponding shutter hinge. There will thus be no difficultyin operatively connecting the upright shafts 7 to the shutter hinges,

even though the construction of the window casing or arrangement ofthe building-may be such that it is impossible tol mou-n-t the upright. shafts directly under the axes. of the blind hinges. It will also be obvious that the sliding'connection. between the polygonal lower ends7 of theupright shafts and the hubs of the sprocket wheels 8' enable the sprocket wheels: to be mounted: at slightly higheror lower elevations: as may be necessary under different circumstances, without in any manner deranging orinterfering with the proper connection. being-made with the blind hinges. I

The sprocket wheels8 under the twoblinds are each connected by a sprocket chain 13 to a larger sprocket wheel 140 which is arranged within the recess D of the wall, the sprocket wheels 14 being mounted upon vertical shafts 15 which project downwardly from the top of the recess. The two wheels 14 are connected by a transverse link 16 which is housed within the recess D, the

ends of the link beingpivoted at 17 to the respectivewheels 14 on opposite sides-of the centersthereof, and the end portions of the link being preferably curved, as indicated at 16 in such a manner as to'provide clearance spaces for the shafts 15 and increase the rotation which can be imparted to.v the sprocket wheels before the link is brought into. engagement with the shafts. Owing'to the fact that thelink: is; connected to. the sprocket Wheels 14 on opposite sides of the respective shafts 15, it'wi-ll beobvious that a turning of one sprocket wheel in one direction will result in a corresponding rotation of the other sprocket wheel in the opposite direction; The two upright shafts 7 are, thus simultaneously turned in opposite directions when the mechanism is operated, thereby enabling the shutters E on opposite sides of the window casing A to be simultaneously opened and closed.

One of the sprocket wheels 14 has a bevel gear 18 rigid with the lower face thereof, said gear 18 meshing with a larger vertically disposed bevel gear 19 which is rigid with an operating shaft 20. This shaft 20 is journaled Within suitable bearings 21 and extends through the inner faceof the wall G into the interior of the building, where it is provided with a crank handle 22. By swinging the crank handle and rotating the operating shaft 20 the two sprocket wheels 14: are turned in opposite directions and the motion is transmitted from these wheels to the respective shutters so that the latter will be opened or closed, depending upon the direction in which the crank handle 22 is moved. A suitablelatch 28 is provided on the crank handle 22, said latch being adapted to engage selected openings 24 in a plate 25 tolock the mechanism and shutters against movement when the shutters have been opened or closed orset in a desired position. The shutters are thus securely locked in an adjusted position, although they can be readily moved by releasing the latch 23 and suitably manipulating the crank handle 22.

Having thus described the invention, What 15 claim as new and desire to secure by Letters Patent, is

1. In a shutter opener, the combination with a window casing, shutter and wall, of a shutter hinge, an upright shaft arranged under the shutter hinge and operatively connected thereto, a sprocket wheel on the upright shaft, a second sprocket wheel arranged within the wall, a sprocket chain extending around the two sprocket wheels, an operating lever on the inside of the wall, and gearing between the operating lever and the inner sprocket wheel.
